I made this Halloween related picture. So I made Diamond Tiara being a zombie. This actually took place in the episode back in season six. It's when Rainbow Dash did the ultimate prank. But it went out of control when all the ponies were turned to Zombies.

I had Diamond Tiara turned into a zombie after she ate the cookies. At least the episode was funny and scary at the same time. So do you guys like this image or the episode? Let me know.
Happy Halloween!
